Specication of Letters Patent.

Application led March 20, 1916, Serial No. 85,249. Renewed March 16, 1918. Serial No. 222,985,

To all whom t may concern:

acitizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful. Improvement in Brake-Rigging, of which improvement-the following is-a speci- -cation This invention relates to brake Vrigging for railway car trucks, and particularly to a brake design of the `clasp type in which brake shoes and brake beams are applied to both sides of Aeach pair of wheels,y

The .object of my invention is to provide an improved rigging bf this character which shall n`ot interfere with the space around the car axles and between the wheels of each pair-,where it is desired to have room for the location of electric motors, generators,

and other equipment, andone-feature comprises brake beams having curved or offset ends 'l extending toward the wheels, and .pivotally attached to the vertical truck levers. Another feature comprises the duplicate sets of vertical truck levers located on opposite 'sides and outside of each pair of truck wheels.

Y In the accompanying drawings: Figure 1 isa half plan of a clasp brake rigging em.- bodying my improvement, the' brake slices and hanger levers bein omitted; and, Fig. 2, a side elevation of t e same with parts of the truck frame indicated in dotted lines.

According to the construction shown, the improvement is applied to a four wheeled truck having brake beams, B1, B2 B3, and B4, located at both sides of each pair of wheels, and pivotally connected at their ends to the 1' lower ends of the vertical truck levers, 1, 2, v40

land ,4, respectively, located outside of the truck wheels. For this purpose the brake lbeams have right angled projections at their ends extending toward and outside of the wheels, and these projections may be in the v form of castings, C1, C2, C3 and C4, to which the respective truck levers are pivotallly ats" tached. yThe body of the brake beam may be turned at a right angle at its ends, and the castings be bolted thereto as indicated at brake'beams B2 and B3, or the castings may be in the form of a right angle and be bolted to; the straight ends of the beams as shown at B1 and B4.

The hanger levers, H1, H2, H3 and H4, arev also pivotally attached at their lower ends Be it knownv that I, THoMAsVL. Bun'rov,V

to the respective brake beams or castin s,

and carry the brake heads and shoes, S1, t 2, S3 and S4, respectively. The 'truck levers, 1 and 2, 3 and 4, are coupled in pairs by the tie rods, 5 and 6, respectively', which are located at intermediate points and above the journal boxes of the wheel axles, so as not 4 to'interfere with f ree access to the journal boxes for inspection, renewals and lubricaH tion. Y i

The truck levers may be operated in various ways, but a preferred construction comprises two sets of intermediate substantially horizontal levers, 7 and 8, one set at each side of the truck, and pivotally connected to the uppercnds of the respect-ive truck levers, 2 and 8, by means of links, 7a and v8". `The truck levers, 1 and 4' at the opposite ends of`tl1e truck, are dead levers,

having fulcrums at their upper ends fixed upon thetruck frame. The intermediate levers, 7 and 8, arejoined by the rod, 9, the

lever, 7, having aviixed fulcrum at 7b, attached by an ordinary link and bracket to the frame, while the lever, 8, is a oating lever pivotally connected at its inner ,end

with a cross equalizer, 10, having a pull 4rod 11, attached at its middle part,

For supporting the intermediate brake beams,vthere may be provided, in addition to the hanger levers, a suspended frame comprising a horizontal bar, 12, and two -vertical hanger bars, 13, the brake beams,

B2 and'BB, being slidaloly supported on the bars, 12, at the opposite sides. lVhen power is applied to the' pull rod, 11, for applying brakes, the movement is transmitted by the equalizer, 10, to the intermediate levers, 8, upon opposite sides of the truck. This actuates the truck levers, 3 and 8, upon opposite sides of the truck. and through rods, 9, and levers, 7, the truck levers, 2 and 1, are also operated so `lthat the force is exerted .throughout the system and the brake shoes A levers.

. ends to the ends ofthe brake beams,

Having now described my invention, what I claim'as new and desne to secure by Letn ters Patent is:

l. In a brake 'rigging for railway trucks.

combination of brake beams applied to both sides of each pair of wheels, vertical truckV levers pivotallyl connected to said brake beams and located outside of said wheels,

hanger levers also pivotally attached to said brake beams, brake shoes mounted on said hangers, and tension rods connecting said truck levers.

3. In a brake rigging for railway trucks having a plurality of pairs of wheels, the

combination of brake beams applied to both sides of each pair of wheels, vertical truck levers pivotally connected to said brake beams and located outside of said wheels, tension rods coupling said levers in pairs, and a pair of intermediate horizontal levers pivotally connected to intermediate truck 4.*In a brake'rigging for railway trucks having a plurality of pairs of wheels, the combination-.rbbrake beams applied to both sides of each pair of wheels, two sets of vertical truck levers, one on each side vof vthe truck, pivotally connected at their lower and located putsid'e of the said wheels, tension Vhaving a plurality rods conneceing said levers at intermediate points in pairs, a double set of intermediate horizontal levers 'pivotally connected to truck levers on opposite sides, and a cross equalizer for actuating said intermediate levers. l

5. In a brake rigging for railway trucks having a plurality of pairs of wheels, the combination of brake beams applied to both sides of eachpair' of wheels, said brake beams having projectionsat their ends eX- tending toward and outside of the wheels, vertical truck levers pivotally connected'to said projections, and tension-rods connecting said truck levers.

6. In a brake rigging for railway trucks of pairs of wheels,the.

combination of brake beams applied to both sides of each pair of wheels, said brake beams having right angled projections at their ends, vertical truck levers pivotally connected to said vprojections outside the wheels, hanger levers pivotally attached at their lower ends to said projections, and tension rods connecting said truck levers.

7. In a brake rigging for railway trucks having a plurality of pairs of wheels, the vcombination of brake beams applied to both sides of eachl pair of wheels, truck levers pivotally connected to the ends of said brake beams, and suspended frames, one at each side of thetruck, and comprising a horizontal bar slidably supporting adjacent in- {ermediate brake beams, and vertical hanger. ars.
